I am Emperor Penguin. Up to four feet (120cm) tall and weighing up to 100lb (45kg), I am the largest of all penguins. To survive in the frigid Antarctic habitat I have a thick layer of fat, and the densest coat of feathers of any bird. During winter we males and females take turns to incubate a single egg. The other mate makes the long journey across the ice from the breeding colony to the open sea to hunt, returning to share its catch.
